Nobody can delete other user's posts except in one specific situation, where they delete their own thread. Which almost never happens.
Except that it happens all the time.
Clear thinking should point out to you that it makes no sense to remove a convenience that benefits the forum more often than it hurts it.
Except that it doesn't. And quite often, it harms more than it benefits, when great, informative exchanges are wiped out because of one dissatisfied user who gets the mod-privelege of deleting the posts of others just because their's was the first in the thread.
Of course if everybody really is seriously doubting their own capacity to decide whether or not to delete their own posts, then perhaps the mods should become babysitters for our own safety!
Counterpoint: By that rationale, each and every person that posts a reply to any thread started by a non-mod must, by definition, lack the capacity to decide whether or not to delete their own posts, because they cede that power, in part, to whoever started the thread.
It doesn't really make much sense to act as though moderators need to spoon feed everybody because one person who isn't even a member of the forum anymore can't handle their own thread in a way that pleases other members.
How is it spoonfeeding?
So rather than just allowing users to edit their own posts, it's preferable to allow someone
who isn't even a member of the forum anymore to delete the content posted by others? How does that make any sense?
The majority seems to favor everybody keeping their ability to manage their own posts though as evidenced by the poll in this thread.
Except that the poll somehow managed to neatly avoid the true heart of the issue.
The fact that the recent events have led to such active discussion and criticism among the community suggests to me that it's an issue that is a significant concern to a significant portion of the users.
I'm afraid I don't see why you want to drag the mods into the discussion. Unless you're suggesting the majority of users here aren't rational.
Two things:
1) If you want to nitpick about mods, you were the one who "dragged them into the discussion" with your babysitter comment.
2) If each thread author effectively has the ability to moderate their own threads, deleting the posts of others for any reason, regardless of site rules, what other purpose do the mods serve? The whole point of a moderation staff is to keep things running smoothly, and 'running smoothly' is something that isn't happening when any normal-level user deletes the posts of others for selfish reasons.
